green: a characteristic usually, but not necessarily exclusively, indicative of this species.
yellow: within the range of variation of this species, but not considered indicative.
red: a characteristic that would preclude this species.
Typical examples of the key marks are shown below (links from text).
If a mark meets the description/illustration, it is a strong pointer to the indicated species;
if it does not, but it is close, this does not necessarily preclude the indicated species.
If the total for any species reaches 100, it can reasonably be assumed to be positively identified.
For some species the maximum only just exceeds 100 and for others is much higher; this reflects the
uniqueness and reliability of the key marks.
